Firework burned but no sparkles or anything!


Recommended Posts

Posted

Yesterday I combined 6 Potassium nitrate, 4 sugar, and 1 aluminum powder then put it in a tube and add fuse to it. I tried to light it, but it didnt do a thing.

 

Today I went to retrieve it and open it to see if it was fuse that was the problem. To my surprise, inside was all charred!

 

 

 

 

What could have caused this? How do I fix this problem?

Sounds like it smouldered over time. What do you WANT it to do?

Yeah. I was hoping that it'd emit sparkles and give off pinkish purplish flame.

 

 

 

 

I was trying to make a fountain.

I've already given you a website with plenty of formulas, which are tried and true. Why not try one of them instead of wasting your time trying to make your own up? I don't know how fine your aluminum is, but for fountains somewhat coarser is better. Also, most fountains require a clay nozzle or choke.

i think the sugar slowed the burn down and all the metal stuck to it even sugar rocket fuel doesnt really make a long flame good for fountains, you cant make coloured flames with kno3 just pinkish and orange

make one of these you wont be dissapointed mine was quite scary really with 6-8ft flame and sparks every time it spat i thought it was going to blow next time i would add 8-10% metal and maybe make the nozzle a tad bigger you can do this in 15 minutes

but youll need some charcoal.
